ASTM standard for Welded fittings

Pipe fitting work is done in many different settings: HVAC, manufacturing, hydraulics, refineries, nuclear-powered Super carriers and Fast Attack Submarines computer chip fab plants, power plant construction and other steam systems. Pipe fitters (sometimes called simply “fitters”) are represented in the USA and Canada by the United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States and Canada.

Fitters work with a variety of pipe and tubing materials including several types of steel, copper, iron, aluminium, and plastic. Pipe fitting is not plumbing; the two are related but separate trades. Pipe fitters who specialize in fire prevention are called Sprinkler fitters, another related, but separate trade.

Materials, techniques, and usages vary from country to country as different nations have different standards to install pipe.
